About Designation Unit and Tolerance for Key Flat Cutting
(1) To align the key flat with the shaft diameter
Unit of designation0.05mm increments possible
V The tolerance is 0-0.1 even when D/2 is designated to fit to the shaft diameter.
(2) To designate arbitrary key flat dimensions
Unit of designation 0.1mm

ESNV H7 -0.01-0.02
※ Note that for sleeves with V dimension tolerance of H7, combination with center pins that have shaft diameter tolerance 0-0.005 is not recommended. The reason for this is the fitting sections S are longer. (Details X P.1309)
